volume of the center sphere = 4/3*PI*r^3
r = 3 ( given in the picture)
so 4/3 * 3.14 *3^3 = 113.04 cubic feet
volume of 1 cone: pi *r^2 *h/3
r = 3 and h=3 ( given in the picture)
so 3.14 * 3^2 * 3/3 = 28.26 cubic feet
there are 4 cones so 28.26* 4 = 113.04 cubic feet
113.04 + 113.04 = 226.08 cubic feet
rounded to nearest cubic foot = 226 cubic feet
2 out of 6 (3 out of 6 if 3 itself is included)
Answer:
Last year's price was $12.50.
Step-by-step explanation:
We'll use the variable x to represent last year's price. First, we have to set up an equation:
.60x + x = 13.25
We get this equation because $13.25 is 6% MORE than last year's price, meaning we need to add the original price to the increase. Next, we combine like terms and solve for x:
.06x + x = 13.25
1.06x=13.25
1.06 r 1 .06 = 13.25 1.06
=$12.50
Last year's price was $12.50.
Really Hope This Helps :) Stay safe folks <3
